Flagg provides information in tabular form on some 5,000 Maine Revolutionary pensioners. Arranged alphabetically, the pensioners are identified by name, rank, service, age, county of residence, remarks such as date of death or town of residence, and source of the information.

The body of this consolidated work is a list of 25,000 Revolutionary War pensioners still living in 1840, with their ages and the names of the heads of families with whom they were residing. Based upon the returns of the Sixth Census of the U.S., the arrangement is by state or territory, thereunder by county, and in the case of some counties, by minor subdivision. Thus a good deal about the origins of settlers of each county of the United States, as well as the magnitude of migration into the various areas of the country, can be gleaned from an examination of this work. The Census of Pensioners is here reprinted with the typescript index to the work prepared by the Genealogical Society of the Church of Jesus Christ of Latter-day Saints in 1965.
